Catalytic Method for the Synthesis of Phosphoryl Isocyanates

摘要

Phosphoryl isocyanates XYP(O)NCO show high reactivity and serve as initial compounds for the synthesis of various types of compounds of potential practical interest:phosphorylated urethanes,ureas,heterocyclic compounds,etc.Although isocyanates of such a type have been known since the mid-twentieth century,no versatile and efficient method of their synthesis from available and cheap initial reagents has hitherto been invented.The reaction of phosphoryl chlorides
